A 2025 study suggests that very low levels of lithium in the brain might be linked to Alzheimer's disease. In mice, certain lithium supplements seemed to protect memory and the brain. But scientists don't yet know if lithium pills are safe or helpful for people.

Cervical dystonia is a movement disorder that causes involuntary, sustained muscle contractions that make the head wobble or rest in abnormal positions. Symptoms can be disruptive, making it hard for people with the condition to drive, dress, or reach for objects.
